In a statement, the Labour MP said: “It is in the best interest of the Home Affairs Select Committee that its important work can be conducted without any distractions whatsoever.

“I am genuinely sorry that recent events make it impossible for this to happen if I remain Chair. I have always been passionate about Select Committees, having served as either Chair or Member for half of my time in Parliament.

“The integrity of the Select Committee system matters to me. Those who hold others to account, must themselves be accountable.”
